Why do you need to Change the Filter?


Air conditioning filters are needed because they keep dust out of the home and provide clean, cool air. You will want to make sure that the system is well maintained so it works efficiently. If you are not sure how often to clean or check the filter, make sure to contact us. We can advise you on the schedule you need for your home and air conditioning system.

Keeping the Filter clean

The air conditioning coil is designed with closely spaced fins that are pressed on the actual refrigerant tubes. These fins collect a lot of dust and dirt. An air conditioner’s filter is what prevents dust and grime from building up on these coils, besides improving indoor air quality as well. Filters come in a variety of sizes and can be either permanent or washable.

Old and dirty air filters in an air conditioner will have a negative impact on the performance of the system. This causes it to cool ineffectively and affect the quality of air inside the room or house. This will put people with asthma and allergies at greater risk, as well as waste energy and money.

Issues with dirty filters

Dirty and clogged air conditioning filters lower the energy efficiency of an air conditioner. The energy that is wasted will pollute the environment and add to the greenhouse gas emissions, further compounding the problem of global warming. Clogged air filters will cause the unit to pull more energy while delivering less cooling. This imbalance will have a negative effect on the overall environment.

Cleaning the air conditioning filters regularly will not only improve energy efficiency but also speed up the cooling process. It will also reduce the need to have the air conditioner on for long periods of time. This would help in reducing the power bill and enable homeowners to save on power and maintenance of the air conditioner as well.

Clean air

Clean air conditioning filters help provide cleaner indoor air. It also reduces the incidence and occurrence of lung and breathing disorders, such as asthma, allergies and related diseases. Indoor air quality plays a major role in your respiratory health. Keeping air conditioner filters clean and dust-free will help improve the indoor air quality and keep the home allergen-free.
